Was wondering if anyone had any experience or knows of someone who works on Mackie equipment. Particularly a powered mixer 808s. This is been very gently used and when I went to turn it on the other day LEDs pegged to red and will not release. It seems to be operating fine not overdriving, microphones work, instruments work at normal levels, no over heating and yet the LEDs are pegged. Appreciate any suggestions or referrals to tech people
